Here's another possibility. Apparently in those areas of Greece that were under Venetian control, the Greek Catholic population survived. What would it take to get the Campanians/Apulians/Maltese/etc. to become Eastern Rite (Greek) Catholic, instead of Orthodox, in this scenario, or have part of the population Eastern Rite Catholic?
I don't see Rome giving them the autonomy needed for this. I think they would be brought under direct Roman control.
